I claim:

vl. A closure comprising a cylindrical elo- Vsure'member having a closed end and a noncircular abutment' extending ,fromv said closed end, anoperating memberextending from said closed end and interlocked with said noncircular.abutment .to transmit rotary thrusts to said cylindrical closure membe-igan'd securing means whereby said members are unitedv to prevent separation ofthe interlocking elements. Y' Y A. 'sing a cylindrical closuremember having a closed end and van abutmentyformed integral withA and extendiiigrfrom said closed end, an operatingmember extending from' said closed end andinterlocked with said abutment to transmit rotary thrusts to said cylindrical closure member, and solder whereby said members are prevent united to prevent separation of the interlocking elements.

8. A closure comprising 'a cylindrical closure member having a closed end' and an 'abuti'nent formed integral lwith and extending outwardly from said 'closed end, said cylindrical closure' member and its closed end being made of a single piece of sheet metal, and a sheetmetal operating member coinyprising` a web and a non-circular marginal `to Veach other to prevent separation ofthe interlocking` elements.

4. A closure comprising a cylindrical clo- Vsure member having a closed end and a noncircular abutment formed integral with and extending outwardly from' said Iclosed end, said. cylindrical closurey member Vand its ,closed end being made of a single piecevof sheet metal, and a sheet metal operating member comprising a web and a non-circular marginal flange extending from the outer edgeof said web, said non-circular abutment being interlocked with said web so as to transmit rotary thrusts from said oper-k atingmeinber to` said closure member, and

said members being l solde-redto each other to separation ofthe interlocking elements. y i l y 5. A can closure comprising a cylindrical sheet metal member provided with screw threads and having a closed end with an internal 'seat for the can to be closed, a noncircular abutment formed integral with said closed endand extending outwardly therefrom, and a sheet metal operating member comprising a web soldered to the outer face ofl said closed' end and a non-circular margi nal flange extending from .the edge' of said web and surrounding saidcylindrical membergzsaid web having a non-circular opening conforming to said abutment, and the side faces of said abutment being surrounded by and adjacent to the-walls of said opening so as'to cooperate therewith iii-preventing independent rotation of said sheetmetal inem-r bers; 7. y ln testimony that l claim the foregoing l hereunto ailix my signature.
